Cov fwj txhaj tshuaj, ua ib pawg tseem ceeb ntawm cov thawv yas kom zoo nkauj, siv dav hauv kev ntim khoom tawv nqaij thiab pleev xim vim lawv cov txiaj ntsig zoo, suav nrog kev tsim qauv yooj ywm, kev ua haujlwm siab, tus nqi tswj tau, thiab kev ua haujlwm zoo heev.

Polypropylene cov fwj yas kom zoo nkauj yog tus cwj pwm los ntawm kev ua semi-pob tshab mus rau opaque (nrog rau kev ntxiv cov neeg sawv cev ci ntsa iab), qhov ceev qis (lub teeb), kev tiv thaiv tshuaj zoo heev (tshwj xeeb tshaj yog tiv thaiv roj thiab cov kuab tshuaj), kev tiv thaiv kub zoo (tuaj yeem ua kom huv si), qhov nyuaj siab, kev tawv zoo, thiab tus nqi qis. Qhov tsis zoo suav nrog kev pob tshab qis dua piv rau PETG / AS, qhov ua tau brittleness ntawm qhov kub qis, kev cuam tshuam rau UV hluav taws xob (xav tau ntxiv cov stabilizers UV), thiab qhov ci ntsa iab qis dua. Lawv tuaj yeem siv rau cov thawv tshuaj pleev ib ce, lub raj mis tshuaj pleev ib ce, lub raj mis tshuaj zawv plaub hau, lub raj mis da dej gel, cov raj mis tshuaj pleev ib ce, lub hau, cov khoom siv taub hau twj tso kua mis, thiab lwm yam, thiab yog ib qho ntawm cov khoom siv txhaj tshuaj molding tshuaj pleev ib ce siv dav tshaj plaws.

Polyethylene cov fwj yas kom zoo nkauj, ua los ntawm HDPE, yog cov yam ntxwv los ntawm kev tsis pom tseeb lossis ib nrab pob tshab, siab tawv, zoo rigidity, zoo tshuaj lom neeg tiv taus (tshwj xeeb tshaj yog tiv thaiv cov kua qaub thiab alkalis), pheej yig, thiab yooj yim ua. Lawv feem ntau siv rau cov thawv tuab dua, lub hau, thiab lub raj mis da dej gel loj. LDPE/LLDPE yog tus yam ntxwv los ntawm nws cov qauv mos dua, zoo dua toughness, thiab me ntsis pob tshab dua HDPE. Nws feem ntau siv rau cov raj mis, lub hau raj mis, thiab lub cev raj mis extruded. Nws tuaj yeem siv rau kev ntim khoom rau cov khoom ntxuav (gel da dej, tshuaj zawv plaub hau), lub thawv tshuaj pleev ib ce, ntau yam lub hau raj mis (tshwj xeeb tshaj yog lub hau sab hauv / gaskets xav tau kev sib khi zoo), thiab cov raj mis.

PETG cov fwj yas kom zoo nkauj muaj cov yam ntxwv los ntawm kev pom tseeb siab, ci ntsa iab siab (piv rau iav), tiv taus kev cuam tshuam zoo heev, tiv taus tshuaj lom neeg zoo, yooj yim luam ntawv thiab kho kom zoo nkauj (kub stamping, luam ntawv npo, thiab lwm yam), thiab rov ua dua tshiab. Qhov kub ua haujlwm qis dua PET. Qhov tsis zoo yog tus nqi siab dua PP/PE, tiv taus cua sov nruab nrab (feem ntau qis dua 70 ° C), thiab qhov nyuaj qis dua me ntsis piv rau AS. Nws tuaj yeem siv rau cov fwj tshuaj pleev ib ce siab, fwj toner, fwj tshuaj pleev ib ce, fwj tshuaj tsw qab (thaum xav tau cov qauv zoo li iav), thiab ntim khoom nrog cov kev xav tau siab. Nws yog qhov kev xaiv nrov rau kev txhim kho lub koob npe nrov ntawm cov khoom.

Txhaj tshuaj pwm cov fwj yas kom zoo nkauj yog cov khoom siv ntim khoom zoo nkauj uas siv thev naus laus zis ntau, siv dav, thiab pheej yig. Kev nkag siab zoo txog cov khoom siv, cov txheej txheem, cov qauv nqi, thiab cov kev cai tswj hwm zoo yog qhov tseem ceeb rau cov hom lag luam los tsim cov ntim khoom uas ua tau raws li lawv cov kev xav tau, muaj kev nyab xeeb, txhim khu kev qha, thiab sib tw, thiab rau cov neeg yuav khoom kom tswj tau cov khoom xa tuaj, tswj cov nqi, thiab txo cov kev pheej hmoo.
